Long time since posting on the forum, typical that a fault has brought me back.
My car decided yesterday afternoon to start running really rough.. like it was misfiring. I ran a quick scan with a code reader I have (not vag-com) which showed no faults and the EML light has not popped up, neither has the low oil / oil pressure warning.
I took a look at the plugs today and found that in first cyclinder (far left) there was oil covering the electrode but the others were fine. Gave the contacts on the coilpack a clean and replaced the plug with a spare. Started her up but no improvement. There is also a strong smell from the exhaust and when idling the engine makes a audible knock.
I am clueless as to what is wrong, any ideas guys??
